Do not disassemble the high
voltage motor connector. The
high voltage motor connector
may contain residual high
voltage. Coming in contact
with high voltage may result
in death or serious injury.
Your vehicle's hybrid system
should only be inspected or
repaired by an authorised
HYUNDAI dealer.
WARNING
Do not disassemble or assem-
ble the high voltage battery
system. Doing so may result
in electric shock, causing
death or serious injury.
If you disassemble or assem-
ble hybrid system compo-
nents improperly, it may dam-
age the performance and reli-
ability of your vehicle.
If electrolyte comes in contact
with your body, clothes or
eyes, immediately flush with a
large quantity of fresh tap
water. Have your eyes exam-
ined by a doctor as soon as
possible.
WARNING
Do not pile up any items in an
area behind the high voltage
battery. In a crash, the battery
may become unstable, or its
performance may degrade.
Do not apply strong force nor
pile up any items above the
luggage compartment. Such
an attempt may distort the
high voltage battery case,
causing a safety problem or
degrading the performance.
Be careful when loading flam-
mable liquid in luggage com-
partment. It could cause oper-
ational and safety degrada-
tion if the liquid leaks and
flows in high voltage battery.
CAUTION

H53
When the vehicle is paint baked,
do not bake over 30 minutes in
70°C or 20 minutes in 80°C
degree.
Do not wash the engine compart-
ment, using water. Water may
cause an electric shock and dam-
age the electronic components.
NOTICE
Never use the package mod-
ules (high voltage battery,
inverter and converter) for any
other purpose.
Do not use an unauthorised
battery charger to charge the
high voltage battery. Doing so
may result in death or serious
injury.
Never locate the high voltage
system near or in a fire.
Never drill into or strike the
package module. Otherwise, it
may be damaged. An electric
shock may occur, resulting in
serious injury or death.
WARNING
Never assemble or disassemble
the high voltage battery system.
If you assemble or disassem-
ble the high voltage battery
system, the durability and per-
formance of the vehicle may be
damaged.
When you want to check the
high voltage battery system,
have the vehicle checked and
inspected by an authorised
HYUNDAI dealer.
Do not touch the high voltage
battery and high voltage cable
connected to motor (orange
colour). Severe burns and elec-
tric shock may occur. For your
safety, do not touch the cover
of electronic components and
electronic cable. Do not remove
the cover of electronic compo-
nents and electronic cable. In
particular, never touch the high
voltage battery system when
the hybrid system in operation.
It may result in death or serious
injury.
WARNING
This hybrid vehicle uses the
hybrid battery system inverter
and converter to generate high
voltage. High voltage in the
hybrid battery system is very
dangerous and may cause
severe burns and electric
shock. This may result in seri-
ous injury or death.
For your safety, never touch,
replace, disassemble or remove
the hybrid battery system
including components, cables
and connectors. Severe burns
or electric shock may result in
serious injury or death when
you fail to follow this warning.
When the hybrid battery sys-
tem operates, the hybrid bat-
tery system can be hot. Always
be careful because burns or
electric shock may be caused
by high voltage.

Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Unleaded
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 or higher. (Do not use
methanol blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.NEVER USE LEADED FUEL.
The use of leaded fuel is detrimen-
tal to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult an
authorised HYUNDAI dealer for
details.)
NOTICE
NOTICE
Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

Introduction
Petrol containing ethanol
Ethanol [E-10], a mixture of petrol
and ethanol (also known as grain
alcohol), is marketed along with or
instead of leaded or unleaded petrol.
Do not use petrol containing more
than 10% ethanol, and do not use
petrol or ethanol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using ethanol of any
kind if driveability problems occur.
Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Petrol containing more than 10%
ethanol.
2. Petrol or ethanol containing
methanol.
3. Leaded fuel or leaded ethanol.Never use fuel which contains
methanol. Discontinue use of any
gasohol product which impairs
drivability.
Other fuels
Using fuel additives such as:
- Silicone fuel additive
- MMT (Magnanese, Mn) fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalyst, or abnormal cor-
rosion, and may cause damage to
the engine resulting in a reduction in
the overall life of the powertrain.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
NOTICE
NOTICE

Use of MTBE
HYUNDAI recommends avoiding
fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight) in
your vehicle.
Fuel containing MTBE over 15.0%
vol. (Oxygen Content 2.7% weight)
may reduce vehicle performance and
produce vapour lock or hard starting.
Your New Vehicle Limited
Warranty may not cover damage
to the fuel system and any per-
formance problems that are
caused by the use of fuels con-
taining methanol or fuels contain-
ing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle.This type of fuel can reduce
vehicle performance and damage
components of the fuel system, engine
control system and emission control
system.
Fuel Additives
HYUNDAI recommends that you use
unleaded petrol which has an
Octane Rating of RON (Research
Octane Number) 91 or higher.
For customers who do not use good
quality petrols, and have problems
starting or the engine does not run
smoothly, one bottle of additive added
to the fuel tank is recommended
according to the maintenance sched-
ule (refer to chapter 7, “Normal
Maintenance Schedule”).
Additives are available from your
authorised HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.

Introduction

This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorised
electronic devices.By following a few simple precautions
for the first 1,000 km (600 miles) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
Whilst driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer-
gencies, to allow the brakes to seat
properly.
